Abstract

Leiomyoma is a benign solitary tumor which is originated from a smooth muscle cell and grows slowly. It is most commonly found in the uterus and can develop anywhere that smooth muscle is present, including esophagus, lower extremity, stroma of GI tract, and pleura. However, the occurrence of leiomyoma in the hand is so uncommon. We present one case of solid type leiomyoma found in the right 4^th finger of a young woman.

Photograph shows a protruding mass in radial aspect of the right 4^th proximal phalanx.

Figure 2.

Radiograph shows a round soft tissue lesion on right 4^th proximal phalanx, but neither bony erosion nor calcification was observed.

Figure 3.

Ultrasonograph shows an ovoid-shaped cystic lesion in right 4th finger proximal phalanx, which measures 0.7×0.4×0.7 cm. (A) Axial view, (B) Saggital view, (C) Doppler: No vascular flow was observed in the lesion.

Figure 4.

Photographs show a yellow-brownish soft tissue mass. (A) The mass was dissected meticulously. (B) The mass removed was about 1×1×1 cm in size.

Figure 5.

Pathologic findings: (A) Tumor cells are composed of intersecting fascicles of well-differentiated smooth muscle cells that are characterized by a spindle shape, eosinophilic cytoplasm and blunt-ended, cigar-shaped nuclei (×200). (B) Smooth muscle actin is expressed in tumor cells (SMA, ×200).
